## Caption

Jewel Cave National Monument is the third-longest cave in the world, with more than 230 miles of mapped passageways, and they're still finding more.

Named after the glittering calcite crystals that line its walls, this underground maze is packed with dramatic chambers, twisting tunnels and rock formations millions of years in the making. The only way to experience it? Join a guided cave tour.

Back above ground, swap cave walls for pine forests on the Roof Trail or Canyons Trail, and keep your eyes peeled for bighorn sheep and other wildlife.

💡 Pro tip: Cave tours are popular for a reason. Book ahead if you don't want to miss out.
